529EGJIFICATION forming part of Letters Patent N 0. 702,974, dated June24, 1902.

Application filed August 8, 1900.

To all whom it 772107] concern.-

Be it known that 1, WILLIAM LESTER LE- LAND, a citizen of the UnitedStates, and a resident of Sisson, in the county of Siskiyou and ImprovedLog-Turner, of which the following is a full, clear, and exactdescription.

The invention relates to sawmills; and its object is to provide a newand improved logturner which is simple and durable in construction andarranged to move a log from the log-deck upon a log-carriage, toconveniently and automatically turn the log over after several boardshave been sawed off, and return the log to position against the knees ofthe head-block on the log-carriage.

The invention consists of novel features and parts and combinations ofthe same, as will be'fully described hereinafter and then pointed out inthe claims.

A practical embodiment of my invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a side elevation of the improvement as applied, thecarriage-track being in section and the partly-sawed and turned-over logbeing held in position on the log-carriage ready to be turned over. Fig.2 is a like view of the same with the log on the log-deck pre- 'paratoryto being rolled upon the log-carriage. Fig. 3 is a similar View of thesame with the log secured in position on the log-carriage. Fig. a is aplan view of the improvement with the parts in position as shown inFig. 1. Fig. 5 is an enlarged side elevation of the dog, thespring-pressed bar, andthe catch for the same in an open position. Fig.6 is a like view of the same with the catch engaging and locking thespring-pressed bar in place, and Fig. 7 is a side elevation of theengine-cylinder and valve mechanism.

Below the log-deck A, adjacent to the carriage A, is pivoted at B apusher or bumper B, adapted to engage with its front face a log forshoving the latter from the log-deck A upon the carriage A. On the upperend of the pusher B is fulcrumed at a a dog 0, pivotally connected at bby a link D with the piston-rod E of an engine E, in which the pistonhas a reciprocating motion to impart Serial No. 26,251. No model.)

a swinging motion to the dog 0 and to the pusherB, as hereinafter morefully described. The dog C is also pivotally connected at c with theupper or curved end F of a bar F, mounted to slide in the pusher B andpressed on bya spring F to normally hold the bar in an uppermostposition. On the bar F is formed a notch F adapted to be engaged by acatch G, fitted to slide in the lower end of the pusherB and pressed onat its outer end by a spring G, carried by the pusher. The outer end ofthe catch G is also connected by a link G with an arm H, loosely held ona shaft H, extending transversely and journaled in suitable be'arings onthe framework for the logdeck A. A spring H engages with one end the armH and is secured with its other end on the shaft H, on which the springis coiled. On the shaft H is arranged a hand-lever H connected by a linkH with the valve mechanism for controlling the motive agent for theengine E, as shown in Fig. 7. Thus the sawyer by manipulating the leverH can impart a turning motion to the shaft H to cause the spring H toswing the arm H and withdraw the catch G from the notch F whenever it isdesired to release the bar F.

The pivots b and c are located on opposite sides of the fulcrum a forthe dog 0, as is plainly illustrated in the drawings, and the free endof the dog 0 is formed with oppositely-extending points 0 C of which thepoint C is adapted to engage the front of the log I when it is desiredto push the log from the deck A upon the carriage A, and the other pointC is adapt-ed to engage the rear of the log I (see Fig. 1) whenever itis desired to turn the log over after it has been partly sawed.

In order to prevent the log from slipping when turning it over after ithas been partly I der rearwardly, so that the link D pulls on lever IIis now moved to cause the motive thereof to form a fulcrum for the logto turn on when drawn to the left by the dog O.' When the several partsswing into the position below the top of the log-deck A, as indicated inFig. 2, then the chain K exerts a pull on the arm J of the lever J toswing the lever below the top of the log-deck A and al low the log I toreadily pass upon the carriage without being obstructed by the lever J.

The operation is as follows: When it is desired to transfer a log I fromthe log-deck A to the carriage A, then the operator manipulates thelever H to cause the motive agent to push the piston in the cylinder ofthe engine E forward, so that the piston-rod E pushes on the link D, andthe latter thereby imparts a swinging motion to the pusher B, so thatthe front face of said pusher engages the log I and shoves the sameforward from the log-deck A upon the carriage A. WVhen the log is inposition on the carriage and the sawyer desires to roll the log aroundon the carriage to bring the log right side up, then the Sawyer releasesthe catch G from the bar F by manipulating the lever H accordingly, sothat the bar F is forced upward by the action of its spring F to imparta swinging motion to the dog 0, which engages with its point C the log Iat the left-hand side thereof to turn the log around while in positionagainst the knee A of the head-block, as is plainly indicated in Fig. 3.The bumper 13 holds the log against the knee A after the log is placedin position and before it is sawed, and the dog 0 is not thrownforward,as described, if the log lands on the carriage right side up. The hook Ois normally in a rearmost position, and it is always thrown back, andmay so remain unless the sawyer manipulates the lever H to disengage thecatch G from the bar F. This is done when the sawyer desires to push orroll the log when first put on the carriage, as above mentioned, or whenthe sawyer desires to hook a log that is partly sawed and is to bepulled over upon the log-deck. Now when the catch releases the bar F thedog is forced in engagement with'the log, as previously mentioned. The

agent to push the piston in the engine-cylinthe dog 0, and as the latteris locked in place by the now-locked bar F and is pivoted on the pusherB it is evident that the latter is swung to the left, so that the dogpulls on the log I and turns the same over, with the end of the lever Jas a fulcrum to move the log I upon the fiat cut-0E portion, and thenthe above-described operation is repeated in this respect, that thepusher I3 is caused to swing upward again to push the log I back uponthe carriage A against the knees A of the head-block.

The power for putting the partly-sawed log upon the carriage andagainstthe head-block is derived from the cylinder through the connecting-rod Dto the pin in the lower hole in 1 the dog 0 and which latter fulcrums ona pin in the largest hole in the dog 0, and hence the dog is caused toswing back and cause the bar to move downward and compress the mainspring F until the catch G engages and ment of the several parts forturning the log over when desired to push the log from the log-deck uponthe carriage.

Having thus fully described myinvention,

I claim as new and desire to secure by Letters Patent- 1. A log turner,comprising a pivoted pusher, a dog pivoted a short distance from one endto the pusher, and provided at the end of its long member withoppositely-pro jecting points, and a power-actuated device connectedwith the short member of the dog, whereby provision is made for turninga log in either direction, as set forth. l
